LOGGING-B'UNK.

. Specification of Letters Patent.

PatentedAug. 4, 1914.`

Application filed December 18, 1913. Serial No. 807,521.

. To all whom it may concern.'

Be it known that I, CHARLES OJDALE, citizen of the United States, residing at Seattle, in the county of King and State of `Washington, have invented a certain new `and useful Improvement 1in Logging-Bunks, of which the following is a specification. I

My invention relates to improvements 1n car bunks and stakes that are adapted to be used on flat cars or trucks whereon logs of timber or other like articles are to be placed for transportation, and the object of my improvement is to provide a strong and slmple car bunk, embodying at each of its ends a car stake that easily and quickly may be moved longitudinally of such bunk whereby such stake always may belplaced snugly against the outermost timbers of the load more securely to hold such timbers in place onthe car.

A further object of my invention `is to provide a stake associated with suitable mechanism whereby it may be tripped from the` opposite side of the car and may be caused to drop below the planeiofnthe top surface ofthe bunk to be completely out of the way when so tripped.

`l accomplish these objects by devices illustrated in the accompanying drawings, in which- Figure 1 is a view in longitudinal vertical section of a `car bunkembodying my 1nvention as it may appear when associated with a flat car that 1s shown in cross-section; Fig..2 is an enlarged view 1n cross-section on broken line a: of Fig. 1; Fig. 3 `is a similar view showing certain portions ofthe mecha-` nismin a different position; Fig. 4L iis a view` 1n cross-section `on broken llne y, y` of Fig.`

2; Fig. 5is a view in perspective of a detail of my inventiona portionof the `saine being broken away more clearlytoillustrate certain other portions; Fig. 6 is a view in perspective of the stake embodied inmy `invention and Figs. 7 and 8 are views in perspective of details of my invention.

Referring to the drawings throughout which like reference numerals indicate like parts 10 is a car bunk having two similarly` con-` structed ends and adapted to be secured to a set of car `trucks or to the deck of a flat car 11, as illustrated in Fig.\1, to extend crosswise thereof, two or more of such bunks thus forming a support on which logs or timbers ma be placed for transportation. ,j

leach end of the bunk 10 is provided with a movable stake 12 that is adapted `when raised to project upwardly as shown at the left end of Fig. l, and when lowered to lie below the plane of the top of the bunk 10 as shown at the right end of Fig. 1. i The stakes 12, 12 are each provided adjacent their lower ends with pivot members 13, 13 that project outwardlyfrom the` opposite edges of such stakes and are adapted to t and move in oppositely` disposed `slots or guideways 14:, 14; that are provided on the inner surfaces ofieach of the side members of the bunk 10, the forward end of each of such guideways 14:, lat beingpreferably left open whereby the pivots 13, 13 ofthe stake 12 easily may bel inserted or removed. The stakes 12 are each provided with an angularly disposed supporting leg 15 that projects r rearwardly and downwardly therefrom by which the stake is supported when in its upright position, the lower` end of the supporting leg 15 being beveled, `as illustrated in Fig. 6, to form a surface 16 that is disposed at an angle to the horizontal, and thesurface 16 being provided with a plurality of peculiarly shaped pawls 17, 17, as shown in Fig.6, that are adapted to fit into correspondingly shaped notches 18, 18 which are formed in an inclined surface 19 of a block 20 on which the supporting leg 15 is adapted to rest when the stake l2 is raised, as shown in Fig. 4, the supporting legl being adapted to project downwardly through a slot 21 provided in the top :of the bunk 10. The block 20, more clearly shown in.Fig. 6is disposed to lie lengthwise be tween the end wall ofthe bunk 10 and a partition 22, as shown `in Figs. 1 and 2, and is adapted to `be moved sidewise, as indicated by broken lines inFig. 2', to permit the supporting leg 15 to drop downwardly through the `slot 21. The mechanism for moving such block 20 sidewise consists in two sets of` shifting members each of which is composed of two peculiarly shaped parts 23 and with a hole 25 through which a pin 26 may be passed to secure such member to the bunk frame 10 and at the other end with a downwardly projecting pivot stud 27 to which an actuating link 28 may be secured, the end of the link 28 being pivotally connecte'dwith a trip rod 29 which extends to aV point that is easily accessible from the opposite side of the car and is there provided with a suitable handheld 30 and with a catch 31 by means of which it may be secured in a fixed yposition.v f

The member 24 is provided at one end with a downwardly projecting pivot stud 32 that isv adapted to pass through a suitable perforation y33 .provided in the member 23, and at the other end with an upwardly projecting pivot stud 311` that is adapted to project within a suitably formed hole 35 in the block 20, one end of the member 24: being adapted to bear against the concave surface of the member 23 and the other end of f the member 21 being positioned within a recess 36 in the block 2O and adapted to bear against the wall thereof, as shown in Fig. 2, the pivot studs 32 and 34 serving to hold, the member 24 in its correct position and the ends of the member 24 serving to receive any thrust tending to move the block 2O to'- ward the side ofthe bunk.

WVhen the bunk 110-is tobe put in use the stake 12 may be raised, as shown in Fig. 1, and the trip rod 29 maybe moved endwise of the bunk to cause the members23 and 24C to move-from the position shown in Fig. 3, into the position-showny in Fig. 2, thus by a toggle movement exertingy aforce,

on the block 2() to move it toward the cen-` ter of the bunk'where it may be stopped by engaging with the downwardly projecting edge of the thickened top portion 37 of the bunk 10, the beveled surface 19 of the vblock 20 being directly below the slot 21 whereby the beveled end 16 of the supporting leg 15 may rest thereon and the pawls 17, 17 may project into and engage with the notches 18, 18 to prevent the stake 12 from `dropping downwardly or moving j outwardly, said i pawls 17,17 and said notches 18,18 being of such shape that the stake 12 easily may be moved inwardly to any desired position, as shown by broken lines in Fig. 1, the pawls 17, 17 riding over the notches 18, 18 when the stake is moved inwardly and engaging with such notches 18, 18 to prevent such stake 12 from being moved outwardly by outward pressure that may be exerted thereon.

When handling logs of large diameter it is not always, possible to yselect logs lof the proper dimensions snugly to fit between stakes that are secured ata fixed distance apart and for this class of'work the ad# the bunks on a car and the. stakes may then be moved tightly against theoutermost logs on either side securely to hold them in position thus preventing the logs from` rolling or the load from shifting sidewisel on the car. l Then the `stake 12 is in itsl raised position it` may be lowered by releasing the trip rod 29 at the opposite side of the carandv of the bunk 10, the angle of the beveled su'r-` face 19 of the supportingblock 20 and the corresponding angle of the. end of the' supporting leg 15 being of the proper inclinak tion to cause the supporting leg 15 easily to slide off of the surface 19 even though a heavy pressure isbeing sustained .by they stake 12.

Manifestly changes in details and form of construction of my car bunk may be resorted to without departing from the spirit of my invention or sacrificing any of its adf vantages. t

What I claim is:

f 1. In a bunker the dass described, the combination with va frame, of a stake associated with said frame, said stake having a beveled portion on its bottom side, and a block, said block having la. beveled portion on which the beveled portionof sai'd stake may rest whereby sai-d stake easily may" slide offfof said block moved sidewise. j j

In a car bunk of the cla-ss described, the combination with a'frame, of a stake associated lwith said frame, a supporting `leg provided on said stake, anda block on which said supporting leg may rest said block being adapted to be Vmoved sidewise to permit said supporting leg to drop downwardly to lower said stake.

`when 4`said block is 3. In a car bunk of the class described, the :l

vcombination with a frame, of a 'stake assof ciated with said frame, pawls provided on said stake, a block on which said sta-ke may rest, said block being provided with notches in which said pawls may engage to prevent said stake from moving outwardly on ysaid framey and means adapted to move said block sidewise to permit said stake to drop downwardly.
